The prevalence of particular fortress types in medieval China, Mongolia, Japan and Korea demanded the evolution of different modes of siege warfare in each country. The wealthy walled towns of China, the mountain fortresses of Korea and the military outposts of Japan each presented different challenges to besieging forces, and this book reveals the diversity of tactics that were developed to meet these challenges. Most of the Far Eastern weaponry of this period originated in China, but was adapted to fit the demands of siegecraft across the region and the individual strengths and weaknesses of each piece of machinery are studied here.

From the 11th century AD, East Asian armies made increasing use of exploding missiles and siege cannon to reduce the fortifications of their enemies. Some of these weapons were very similar to those used in Europe - for example, the heavy siege cannon used in the siege of P'yongyang during the Japanese invasion in the late 16th century. Others, like the Korean hwach'a carts mounting over a hundred rockets that were used to bombard the Japanese at Haengiu in 1593, were very different from their European contemporaries. This book details the design and use of the wide range of weaponry available during this period.
